1. Before vaccinating a kitten, ensure it is healthy, free from colds and diarrhea, has a normal body temperature, is in good spirits, and has a normal appetite. If any adverse reactions occur, wait until the kitten has recovered before vaccinating.
2. Kittens that have just arrived home should not be vaccinated immediately. They should be vaccinated after they have adapted to their environment to avoid stress.
3. Kittens should be 8 weeks old or older.
4. The kitten has not had any contact with or conflicts with other cats before being vaccinated. 5. Cooperate with the veterinary clinic for a physical examination. 
Precautions after kitten vaccination
1. Do not shower. Sufficient protective antibodies are usually produced 7-15 days after vaccination. Showering may cause you to catch a cold or get sick, which may affect the effectiveness of the immunity. If you really can't stand the dirt, you can use dry cleaning powder to wash. Vaccines should be given 7 days after the full immunization program is completed.
2. Avoid using serum and monoclonal antibodies, which are biological products that can temporarily prevent infectious diseases, but they can also neutralize vaccines and affect the number of antibodies produced.
3. Do not go out until you have completed your vaccination course.
4. Do not change food arbitrarily. Do not change food during the immunization period, as this may cause food allergies, which can affect the effectiveness of the cat's immunization.
5. Provide rich nutrition. Cats need a special diet during vaccination periods. These foods are rich in various polysaccharides, which can stimulate the immune system, improve the cat's immunity, and enhance the effectiveness of the vaccination. For example, PetFragrance Immune Polysaccharide Paste. Other foods that boost immunity are also suitable.
